Classroom Resources: Molecules & Bonding
1 – 7 of 7 Classroom Resources
Solubility, Solubility Rules, Solute & Solvent, Intermolecular Forces, Chemical Bond, Ionic Bonding, Covalent Bonding, Polarity, Intermolecular Forces, Intramolecular Forces | High School, Middle School
In this activity, students will use an animation to visualize how ionic and molecular compounds dissolve (or don’t) in water. They will see that if an ionic compound such as salt dissolves, the ions dissociate, whereas the molecules in a molecular compound such as sugar remain intact but are separated from one another by water molecules. They will also see that some ionic compounds, such as chalk, do not dissolve, and the cations and anions remain stuck together.
Intermolecular Forces, Intramolecular Forces, Polymers, History, Interdisciplinary | High School
In this lesson, students will learn about how sticky tape was developed through reading an article. There are a series of activities to help promote literacy in the science classroom related to the reading. This lesson could be easily used as plans for a substitute teacher, as most of the activities are self-guided.
Ionic Bonding, Bond Energy, Electronegativity, Intramolecular Forces, Lewis Structures, Polarity | High School
In this lesson, students will discover that dissolving salts changes the temperature of a solution even though it is a physical change. Students will first collect data during an investigation to compare the temperature change when dissolving three different salts (NaCl, KCl, and CaCl2). Then students will use magnets to construct an explanation of the temperature change based on collision of particles and properties of the metals.
Molecular Structure, Intermolecular Forces, Ionic Bonding, Covalent Bonding, Metallic Bonding, Polarity, Intramolecular Forces, Chemical Properties, Physical Properties, Interdisciplinary, Culminating Project | High School
In this project, students will develop a presentation to explain how and why a specific material can solve a problem. The explanation will involve researching the properties of the material and how its properties are suited for solving a specific problem.
Solubility, Intermolecular Forces, Intermolecular Forces, Mixtures, Intramolecular Forces, Polarity, Observations, Physical Properties, Chemical Properties, Identifying an Unknown, Mixtures | High School
In this lesson, students determine whether unknown substances are polar, nonpolar, or ionic by testing their solubilities.
Intermolecular Forces, Solubility, Intermolecular Forces, Intramolecular Forces, Polarity, Lewis Structures, Molecular Structure, Solute & Solvent, Mixtures, Melting Point, Freezing Point, Boiling Point, Physical Properties, Graphing, Mixtures | High School
In this lesson, students investigate how intermolecular forces effect physical properties by investigating substances’ melting points as well as solubility.
Ionic Bonding, Naming Compounds, Intramolecular Forces, Ions | High School
In this activity, students will construct ionic compounds by balancing the charges on cations and anions.
